Diagnostic Trouble Codes Table
WARNING: This page is about a different car, the 2005 Suzuki Reno and 2005 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
When the sensing and diagnostic module (SDM) detects any problem it illuminates the airbag warning indicator and stores the diagnostic trouble codes (DTCs).
The supplemental inflatable restraints (SIR) diagnostic system check must be always the starting point for any SIR diagnosis. The diagnostic system check reveals diagnostic trouble codes (DTCs) through the use of scan tool. It also checks for proper airbag warning lamp operation.
The two types of DTCs that may be recorded are as follows:
- Active DTCs represent malfunction being detected during the current ignition cycle. Active DTCs are stored in random access memory (RAM).
- Historic DTCs represent malfunctions detected since the last time the historic memory was cleared. Historic DTCs are stored in the electrically erasable programmable read-only memory (EPROM).
